APPARATUS FOR MANUFACTURING ICE.

Specification of Letters Patent.

Patented May 21, 1912.

Application filed August 22,1910. Serial No. 578,323.

To all-whom "it may concern:

I Be it known that I, VVILLIAM E. Amni- STEAD, a citizen of the United States,residing at Sandersville,.in the county of Washingtonand State of Georgia, have invented certain new and useful Improvements in Apparatus for Manufacturing Ice; and I do hereby declare the following to be a full,

clear, and exact description of the invention,

such as will enable others skilled in the art to which it appertains to make and use the same. a y

This invention relates to an apparatus for manufacturing clear and pureice from raw water, and the primary object of the mvention is to conduct'raw waterreduced to a verylowtemperature to the ice forming cans and conducting said water therethrough continuously during the process of freezing, carrying same back to the forecooler or inltial receptacle for first cooling the raw water, a filtering mediumgbeing introduced between the discharge end of the ice formingtanks and the torecooling chamber,

In carrying out my process I may introduce the raw water tothe ice forming cans either from the top or conducting the same back to the forecoohng chamber from the top or bottom, as the case may be. 7 r

In the accompanying drawings, however, illustrating a practical arrangement of an apparatus for carrying on my process, and for simplicity of illustration, I have simply shown an. apparatus in which the water is introduced from the forecooling chamber to the to of the ice forming cans and is conducte from the bottom of the ice forming cans; during the process of formation of ice and carried back to the forecooling chamber. It will be understood that my invention is to any particular but for the purpose of disclosure reference is had to the illustrating one form of apparatusm which like characters designate" the same parts in the several views, and in which- Figure. 1 is a longitudinal sectional view throu h a series 0t ice forming cans containef within an outer brine tank, the forecooling chamber, pump and other apparatus section on the line 2-2 of Fig. 1, showing one of the division plates in elevation. Fig. 3 is a plan view looking downon the outer from the bottom and elevation. Fig.2 is a cross brine tank and the ice forming cans, the cover being removed,-and Fig. 4 is a sec tional detail of one form of water tight jointbetwcen the outer pipe and the bottom of each ice forming can.

1 is an outer brine tank provided with an inlet 2 and an outlet 3 leading from and returning to a suitable brine cooling tank,

'not shown. The bottomof'the brine tank is provided with a layer of insulation mater al 4, and below said insulation material is disposed a pipe 5 headed at one end, as at 6, and extending outwardly, as at 7, to a reservoir 8 communicating with a pump 9 driven by a suitable steam or other engine 10, the pump 9 having a conduit 11 leading to a forecooling apparatus 12, common to ice manufacture, and a filter 13 being disposed betweco the pipe 5 and the forecooling chamber 12, but preferably located in the pipe line between the pump 9 and the fore cooling chamber 12.

The insulation 4: is apertured, as at 14, to receive a nipple 15 forming part of a T joint, the nipple 15 of which spreads out to form a semi-cylindrical socket 16 adapted to snugly receive a ball member 17, connected with the bottom of each ice forming can 18 located in the outer brine tank 1 within compartments 19 formed by the division plates 20 extending laterally across said outer brine tank 1 and provided with a vertical series of apertures 21 forming. communicating passages between said compartments 19.

It will be understood that the ball" and socket connection just described and shown 7 more clearly in Fig. ,4 is only one of several water tight connections that might be made between the outlet pipe 5 and the ice formmg cans 18. It w1ll also be observed that the ball member 17 is provided with a port '17 theret-hrough which registers with the 0 rubber or other proper mabore of the nip le 15, and, as shown, a suitable packing terial 16 may be introduced between the ball and socket members of the joint to make the water tight joint more effective.

22 designates a cover for the outer brine tank, and this cover'22 is provided with a headed inlet pipe 23 provided with nozzles or nipples 24 projecting through said cover and extending a predetermined distance down in each oft/he ice ,forming came 18. Oneend of this pipe 23 is connected by means of a flexible connection 25 with the forecooling chamber 12 and enters said forecooling chamber or reservoir at the top thereof. It will be also observed that the pipe 7 enters the auxiliary reservoir 8 at the top thereof, a little below the top of the ice forming cans, the object being to maintain the level of the water in the ice forming cans so as not to overflow same.

In carrying out the process through the apparatus hereinbefore described raw water of a very low temperature from the forecooling chambers is conducted through the flexible pipe 25, the inlet pipe 23 and the nozzles 24 into the ice forming cans 18, which will fill up to the level prescribed by the discharge from the pipe 7 into the reservoir 8. After this level has been reached the water is continuously circulated through each of the cans, passing through the water tight joint 15, intothe pipe 5, through the pipe 7 into the reservoir 8, from whence it is pumped by the pump 9 back again to the forecooling chamber 12, a filter being disposed in the conduit between the pump and the forecooling chamber. Thus a continuous circulation of purified raw water, at a very low temperature, passes through the cans during the freezing process, and the nozzles being centrally disposed of the cans and the outlets therefrom being opposite the nozzles, as the ice forms around the sides achannel is maintained centrally of the block until final congealing takes place. If the contents of one of. the cans should freeze through more quickly than the other it does not affect the operation of the other cans.

It will be understood that the cooling brine introduced at 2 thoroughly circulates around the ice forming cans .in the chambers 19, passing from one compartment to the other through the Vertical series of apertures 21 and division plates 20. It will also be understood that the fiexible connection 25 will allow of the ready removal of the cover 22 from the tanks without disconnecting the pipe 23 from the forecooling chamber. It will also be obvious that while I have described the apparatus as comprising a single series of ice forming cans and a single brine tank, several series may be coupled up by suitable headers. It will also be obvious that where the invention is used with a single series of cans or several series, a suitable outlet is provided for draining off the brine when the ice is to be harvested, and this is essential in. order that the brine tank will not flood into the pipe 5 when the ice forming cans are withdrawn. A sim le illustration of this is shown at the left of Fig. 1, in which the inlet brine pipe is provided with a pipe 26 having a cook 27 and suitably discharging back into the brine cooling tank, not shown. It will also be understood that the outlet from the forecooler will be provided with a cans, and

suitable valve, as indicated at 28.
